### TL;DR This vulnerability affects all Kirby sites with enabled `languages` option that might have potential attackers in the group of authenticated Panel users. If you have disabled the `languages` and/or `api` option and don't call any methods in your code that cause a write access to languages (language creation, update or deletion), your site is *not* affected. ---- ### Introduction Kirby allows to restrict the permissions of specific user roles. Users of that role can only perform permitted actions. Permissions for creating and deleting languages have already existed and could be configured, but were not enforced by Kirby's frontend or backend code. A permission for updating existing languages has not existed before the patched versions. So disabling the `languages.*` wildcard permission for a role could not have prohibited updates to existing language definitions. ### Impact The missing permission checks allowed attackers with Panel access to manipulate the language definitions. The language definitions are at the core of multi-language content in Kirby. Unauthorized modifications with malicious intent can cause significant damage, for example: - If the `language

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
